Question

Suppose you're an astronaut and you're sitting in a 6000kg space capsule riding on a 4000 m x 8000 m sail (whose mass is included in the 6000 kg). You're orbiting in the vicinity of a distant bright hot star giving off light with an intensity 8 x 10^9 W/m^2 at a distance where the gravitational Acceleration is 30 m/s^2. Find a.) the radiation pressure on your sail. B.) the force of light on your sail. C.) is it strong enough to escape the star?
